    Answer:

    The take off time is equal to 41.66s.

    Explanation:

    Given that,

    The initial speed of the airplane, u = 0

    Acceleration, a = 2 m/s²

    Let v is the take off time. Using first equation of motion,

    v = u +at

    Put v = 300 km/hr = 83.3 m/s

    So,

    t=\dfrac{v}{a}\\\\t=\dfrac{83.33}{2}\\\\t=41.66\ s

    So, the take off time is equal to 41.66s.
